I've pretty much decided that I need to start over on my entire manuscript. I blame the Hobbit, which reminded me what good story can really be.
I don't view this as bad thing at all. In fact, it's sort of a relief, and maybe a bit of a cop-out. I was struggling so much with the revisions. I think what I really need, now that I understand my direction a bit better, is to just start with a clean page...and see what happens.
